The ETX 3.0 specification offers all of the benefits of the original ETX standard while adding 2 Serial ATA interfaces. This is done without changing any of the ETX pin designations, making new modules 100 percent pin-to-pin compatible with previous versions. It ensures long-term support for the vast number of embedded application solutions based on these already highly integrated COMs including medical, gaming and entertainment, military and aerospace.
Modules designed according to the ETX 3.0 specification integrate two SATA ports via two slim line connectors designed onto the top side of the CPU Module in the vicinity of X4. The module or carrier board ETX connectors do not require any changes to take advantage of the faster SATA hard drives.
- two SATA ports supported
- 100 percent ETX pin-to-pin compliant
- no carrier board changes
- continued ISA support, along with Ethernet, USB 2.0, graphics, audio and other features
- multivendor standard
